Application August 15 1934, semi No. 739,954 1 claim. (o1. 251-121) My invention relates to new and useful improvements in the process of andy apparatus for cooling air preparatory to introducing it"into a building, andhas for its objects; to provide an 5 air cooling `system for the interior of buildings which is permanent, requires little attention, is extremely cheap and simple to operate, and in which the elements of the earth formation, including water which may be present therein, act as the heat transfer agent to absorb the heat from the air and to lessen its water content, prior to its passage into the interior of the building to be cooled.

With the above and other objects in view, which will appear as the description proceeds, my invention consists in the novel features hereinafter set forth in detail, illustrated in the! accompanying drawings, and more particularly pointed out in the appended claim.

Referring to the drawings in which like nu' merals designate similar parts thruout the several views:

Fig. 1 is a view in perspective o f a building the l interior of which is to b'e cooled, together with a view in perspective of my cooling apparatus connected with said building, a part of said apparatus being cut away to expose another part to view.

Fig. 2 vis a view in side elevation of my primary air cooling chamber, with ducts thereto and 30 therefrom and of a sump in which water 4may collect from said chamber, and also of my secondary air cooling chamber connected into said irst chamber.

Fig. 3 is a view in cross section of said air cooling chambers.

Fig. 4 is a view of the same in front elevation.

Fig. 5 is a top plan view of the same, with a part of the top broken away to expose to view a part of the interior of the primary air cooling chamber. l

I represents the building tobe cooled by my air cooling system, and 2 the intake duct and 3 the discharge duct into and from my heat exchangers which are my air cooling chambers above mentioned. l represents a fan to force air into duct 2, and 5 represents a ian to draw air from duct 3 and discharge the air into said building.

6 represents my primary air cooling chamber for cooling the air passed therethru and 1 represents my secondary air cooling chamber or coolerv in or otherwise present in said coolers, may collect and be removed therefrom thru duct I0 by a pump in well Il, with said pump operated by a pump head I2 located in the basement of the building. A bleeder Il may also be provided in 5 duct 3 into well II to drain water from said duct. All of the above appears generally in Fig. 1 of the drawings. It is obvious that coolers 6 and I A may be buried in the ground at any des'ired'depth,

and that if desired said coolers may be kept moist 10 by permittingwater to percolate thru the ground about them, and that water may be supplied for that purpose thru'water ducts above and about said4 coolers, and that the heat exchange would be hastened by so doing Vunder certain conditions 15 of the earth formation, and, that if water passed about said coolers as if an underground stream ,A of water lay in the strata in which said coolers are placed, said water would facilitate the heat exchange between the airpassing thru the coolers 2o and the earth formation. It is also to be noted that said coolers are of very large air capacity and that the cavities in said air cooling chambers may be suiliciently large for a full bodied man to enter therein.V It is preferred to construct the coolers out of durable material such as zinc or non-corrosive material the nature of which would depend upon the chemical conditions of the earth in which said coolers were to be buried, and that the same be made out of light material and the same encased in a mass of water proof cement so that the cement casting itself will provide the cavities of the coolers in event the material originally constituting the shell of the coolers may have been eaten away.

Directing attention specifically to the remaining drawings, cooler 6 is preferably made with large wide and broad cavities I3 which are ar-v ranged to form a zigzag passageway. The air to be cooled is caused to travel therethru in the direction indicated by the arrows. About said cooler 6 is coiled the secondary cooler I which is shown in the drawings as being in the form of a large spiral cavity connected at its topwrwith the top of the cavity in the primary air cooling 45 chamber and proceeding downwardly to connect with duct 3. 'I'he air travels thru the secondary cooler in the direction indicated by the arrows.

A manhole I5 may be providedin cooler 6, iorl entering said cooler if occasion should ever arise therefor.`

In operation, with the coolers inuplace in the earth formation and with ducts connecting said coolers with said building as shown,- air may be caused to circulate thru the cooling system by operating either fan l or fan 5 or both of them, whereupon the air is taken from the building and conveyed into coolers in the earth Iormation, a heat exchange eiected between the hot air and the cooler earth formation, and the cooled conveyed into the building. When insumcient water is present in the earth formation to effectuate the heat exchange with the rapidity desired, the earth about the cavities may be moistened by water applied thereto and permitted to percolate therethru.

Having thus fully disclosed my invention, what I claim and desire to secure by Letters Patent is:

In an air cooling system for cooling theV inupper of said cavities and a sump connected with y the lower of said cavities.
